Examples

The following example calls GetVersionInfo to get the FileVersionInfo for the Notepad. Then it prints the FileMajorPart in a text box. This code assumes textBox1 has been instantiated.

private:
   void GetFileMajorPart()
   {
      // Get the file version for the notepad.
      FileVersionInfo^ myFileVersionInfo = FileVersionInfo::GetVersionInfo( "%systemroot%\\Notepad.exe" );
      
      // Print the file major part number.
      textBox1->Text = String::Concat( "File major part number: ", myFileVersionInfo->FileMajorPart );
   }

private void GetFileMajorPart() {
    // Get the file version for the notepad.
    FileVersionInfo myFileVersionInfo = FileVersionInfo.GetVersionInfo("%systemroot%\\Notepad.exe");

    // Print the file major part number.
    textBox1.Text = "File major part number: " + myFileVersionInfo.FileMajorPart;
 }

Private Sub GetFileMajorPart()
    ' Get the file version for the notepad.
    Dim myFileVersionInfo As FileVersionInfo = _
        FileVersionInfo.GetVersionInfo("%systemroot%\Notepad.exe")
    
    ' Print the file major part number.
    textBox1.Text = "File major part number: " & myFileVersionInfo.FileMajorPart
End Sub

Remarks

Typically, a version number is displayed as "major number.minor number.build number.private part number". A file version number is a 64-bit number that holds the version number for a file as follows:

The first 16 bits are the FileMajorPart number.
The next 16 bits are the FileMinorPart number.
The third set of 16 bits are the FileBuildPart number.
The last 16 bits are the FilePrivatePart number.

This property gets the first set of 16 bits.
